An embodiment is a system for recording a customer-operator call in an office or call center. Call information (call start time, call end time, call identification ID, extension number, etc.) and recording information (call start time, call end time, recording file) are managed by a database as an index for searching recorded data.

The recorded file of the call may contain personal information (credit number, PIN, etc.) depending on the content of the conversation. If you want to share information with related departments or provide recorded files for educational purposes, you can share them with related departments using the audio disclosure function. However, it is necessary to limit the users who share the recorded file from the viewpoint of information leakage. In addition, when deleting personal information in a recorded file, it is necessary to mask the voice data of the corresponding part by using a general voice processing tool.

Here, as a technique for masking personal information in a recorded file, there is generally a method of downloading the recorded file to a personal computer (PC) or the like and editing it with a voice processing tool. However, this method takes the recorded file out of the system, which may lead to information leakage.
